How to make the Wireframes for these lights?
This is actually really quite straightforward by using Freestyle and the Freestyle SVG Exporter add-on.

Start by enabling the Freestyle SVG Exporter add-on.



The add-on gives you an additional panel in the Render settings that allow you to configure the generation of SVG files. Whenever a frame is rendered, the add-on will also generate an SVG file containing the freestyle layer only.



Setup your mesh and mark the desired edges as 'Freestyle Edge'. Configure Freestyle to render just those edges and render the result.



Once rendered you should find an SVG file alongside the rendered image containing just the freestyle edges.
